In the process production of air ducts, the following main subgroups of equipment (Operations): 1. Preparatory (storage) operation – Guillotine STD-9A, with the possibility of cutting metal up to 2500 mm and thickness of 4 mm to 6 mm. 2. Process operations (Metal forming) operation: – faltseprokatny machine STD-11019, with the possibility of applying seam connecting the workpiece with the thickness of the metal from 0.55 mm to 1 mm. – Bending rolls MEM-3401, designed to get shells (rolling a sheet into a pipe), the minimum diameter of 160 mm and the thickness of the metal from 0,55 mm to 2 mm and a width of 2500 mm.
– A mechanism for bending the sheet MGL-2000/2500M designed for rectangular ducts (ducts) up to 2000 up to 2500 mm and the thickness of the metal from 0,55 mm to 2 mm. – Faltseosadochnye machines STD-28K and TU-28, with the possibility of angular seaming and seam compound lying on the shell or a rectangular box with The minimum diameter of 100 mm, 160 mm and thickness of the metal from 0.55 mm to 1 mm. Rolls bending MEM-3401 Introducing the bending rollers, which are versatile machine for bending sheet in a cold state. Rollers are bending-rolling of blanks from sheet metal of ferrous, nonferrous metals and alloys, with pre-scrap yield no more than 2500 kg / cm.
